The development team behind one of London’s most ambitious sports projects is making some changes to its proposal. Premier League side Tottenham Hotspur has been looking to completely overhaul its home.

The Northumberland Development Project’s specs have been recently changed by the team that includes Tottenham Hotspur F.C., Populous, Allies & Morrison, and Donald Insall Associates, and the plan will be submitted to the London Borough of Haringey in the near future. The old design for the project was submitted in 2007, and the end product has changed in a few respects. The team has increased the seating for the new stadium to around 61,000, added to the housing component of the project, and included an affordable housing element, as well as a new 180-key hotel.

The White Hart Lane stadium is located on Bill Nicholson Way in the London Borough of Haringey. The 1899-built stadium has gone through a number of renovations and refurbishments throughout its history that have allowed it to keep up with the standards of the English Premier League, but a more extensive redevelopment is now required. The project currently seems to be closer to reality than ever with a development deadline slated for 2018, if all approvals come through.

Estimates show that the project will increase Tottenham’s footprint in the borough up to 3,500 jobs created, and approximately $455 million in annual spending to the local economy. The development also includes a new community health center meant to enhance the stadium.

Part of an ongoing partnership with the NFL, the stadium will be fitted with a second, retractable playing surface, up to the league’s specifications. The stadium will also feature a more dramatic aesthetic, as well as the largest single-tier stand in the United Kingdom, a new team museum, public space, and a Sky Walk fitted on the top of the stadium. While the stadium site will undergo these changes, the team will move for the 2017/2018 season to a location still under discussion.
